Specification of Letters Patent.

Patented March 13, 1906.

Application filed May 3, 1905. Serial No. 258,609-

To all whom it may concern:

vided with a plurality of separately-removable leaves or sheets placedone upon another and with antiseptic netting applied to. the opening insaid attachment.

Referring to the accompanying drawings, Figure 1 is a vertical sectionthrough a telephone-receiver and through the attachment secured thereto.Fig. 2 is a rear view of such attachment removed, and Fig. 3 is a frontview of the plate or slide having germicidal netting over thesound-opening.

The attachment (shown secured'upon the receiver h) consists of a rigidbod piece or base 0, provided with sheet-meta or other clasps or clips 9to be bent over or otherwise engage the edge of the receiver, and isprovided with a plurality of separately-removable leaves or sheets I),placed one upon another and secured together and to the base 0 bypasting or otherwise. The pile of leaves or sheets is provided with acentral opening, and the base a is also provided with an opening withwhich that first named registers. Upon its back the body-piece isprovided with attached parallel guides m, made of sheet metal or othermaterial, between which a strip or plate k, (see Fig. 3,) of cardboardor other material, is slidably and removably held. The slidable strip orplate is provided with an opening, and a piece-of netting f,

treated with germicidal substance, is secured over said opening. Whenthe plate 7c is slid into place, the opening thereof coincides with theopenings in the block and in the receiver.

The arrangement described prevents all danger of infection when usingthe telephone, as by tearing off a sheet of paper every time thetelephone is used a fresh sheet absolutely clean and non-infected isprovided, while the netting f absorbs any contagious material there maybe and renders the same innocuous.

What I claim is 1. An attachment for telephones, consisting of a rigidbody-piece and a plurality of leaves or sheets placed one upon anotherand secured to the body-piece, said attachment having an openingextending therethrough, and a removable plate or slide carrying nettingtreated with germicidal substance placed over the opening aforesaid andslidably engaging the rigid body-piece.

An attachment for telephones, consisting of a rigid body-piece and aplurality of separately-removable leaves or sheets placed one uponanother and secured to the bodypiece, said attachment having an openingextending therethrough, and a removable plate or slide carrying nettingtreated with germicidal substance placed over the opening aforesaid andslidably engaging the attachment.

3. An attachment for telephones, consisting of a rigid body-piece and aplurality of separately-removable leaves or sheets placed one uponanother and secured to the bodypiece, said attachment having an openingextending therethrough, a removable plate carrying netting treated withgermicidal substance placed over the opening aforesaid and metallicoverlapping portions securing the plate and attachment together.

4. An attachment for telephones, consisting of a rigid body-piece and aplurality of separately-removable leaves or sheets placed one uponanother and secured to the bodypiece, said attachment having an openingextending therethrough, a pair of guides carried by the back of theattachment, and a removable plate or slide slidably engaged with theguides aforesaid, said plate or slide carrying netting in line with theopening through the attachment and treated with germicidal substance.
